NOTE: Not all accessory shanks will work with the Deluxe Rear Bumper. This bumper requires at least 5-1/4” of unobstructed shank from pin hole to ball mount platform or any gussets. This is to allow it to pass through the 4” pipe and be pinned on the back side of the bumper. The factory receiver must be removed to install the Deluxe Rear Bumper.
